The year was 1944. World
War II was raging and Franklin D. Roosevelt was president. The average price of a new automobile was $1200
and over 200,000 automobiles were registered in the United States. An average family income was $2600 per year
with a minimum wage of 30¢ per hour. The
price of a loaf of bread was 10¢ as was the cost of a package of cigarettes. 300 billion cigarettes were produced that
year.
If you were to ask the average American in 1944, if cigarette
smoking caused lung cancer, the answer would have been a definitive no! It wasn’t until 1952 that the American Cancer
Society declared a link between cigarette smoking and lung cancer. In 1965 Congress made it mandatory for cigarette
manufacturers to include a warning label on every package of cigarettes sold in
the United States.
I can still remember the disbelief, resistance and anger
from both the general public and the scientific community in regard to this
health hazard declaration. In the end,
the connection between cigarette smoking and lung cancer was undeniable and
since that time, study after study has confirmed this.
I find it most interesting to remember that there has always
been a connection between tobacco use and cancer. Even in the absence of public acceptance and
a lack of proof through scientific research, tobacco and cancer have always gone
hand in hand.
Sugar Blues is a book by William Dufty that
was released in 1975 declaring that sugar was an addictive substance that was harmful
to the human body. People scoffed, the
author was called all sorts of names, industry rose up to laugh at the concept
and people in the United States and around the world continued to consume
refined sugar at alarming rates. I,
personally, have been on the anti-refined sugar bandwagon for over 30
years. I too have been called everything
from a quack to a fanatic as a result of my “radical” and unpopular position. But if the truth be known, tobacco is to
cancer as refined sugar is to ill health.
More and more people are now beginning to believe that this
deadly connection does indeed exist, especially in light of the current
scientific research on the matter. I
have included information on one of the latest studies linking sugar
consumption to low intelligence. However,
I would like to bring up the point that inquiring minds have always understood
this connection. And while it is
comforting to have scientific evidence of these nutritional facts, refined
sugar has always been harmful to the human body.
I hope you enjoy the following study and share it freely
with your loved ones. And remember,
science is the observer of truth, not the determiner of it.

Can
Sugar Make You Stupid? A new UCLA study is the first to show how a diet steadily high
in fructose slows the brain, hampering memory and learning — and how omega-3
fatty acids can counteract the disruption. The peer-reviewed Journal of Physiology publishes the findings
in its May 15 edition.
“Our findings illustrate that what you eat affects how you
think,” said Fernando Gomez-Pinilla, a professor of neurosurgery at the David
Geffen School of Medicine at UCLA and a professor of integrative biology and
physiology in the UCLA College of Letters and Science. “Eating a high-fructose
diet over the long term alters your brain’s ability to learn and remember
information. But adding omega-3 fatty acids to your meals can help minimize the
damage.”
While
earlier research has revealed how fructose harms the body through its role in
diabetes, obesity and fatty liver, this study is the first to uncover how the
sweetener influences the brain.
The
UCLA team zeroed in on high-fructose corn syrup, an inexpensive liquid six
times sweeter than cane sugar, that is commonly added to processed foods,
including soft drinks, condiments, applesauce and baby food. The average
American consumes more than 40 pounds of
high-fructose corn syrup per year, according to the U.S.
Department of Agriculture.
“We’re not talking about naturally occurring fructose in fruits,
which also contain important antioxidants,” explained Gomez-Pinilla, who is
also a member of UCLA’s Brain Research Institute and Brain Injury Research
Center. “We’re concerned about high-fructose corn syrup that is added to
manufactured food products as a sweetener and preservative.”
Gomez-Pinilla
and study co-author Rahul Agrawal, a UCLA visiting postdoctoral fellow from
India, studied two groups of rats that each consumed a fructose solution as
drinking water for six weeks. The second group also received omega-3 fatty
acids in the form of flaxseed oil and docosahexaenoic acid (DHA), which
protects against damage to the synapses — the chemical connections between
brain cells that enable memory and learning.
“DHA is
essential for synaptic function — brain cells’ ability to transmit signals to
one another,” Gomez-Pinilla said. “This is the mechanism that makes learning
and memory possible. Our bodies can’t produce enough DHA, so it must be
supplemented through our diet.”
The Testing;
The
animals were fed standard rat chow and trained on a maze twice daily for five
days before starting the experimental diet. The UCLA team tested how well the
rats were able to navigate the maze, which contained numerous holes but only
one exit. The scientists placed visual landmarks in the maze to help the rats
learn and remember the way.
Six
weeks later, the researchers tested the rats’ ability to recall the route and
escape the maze. What they saw surprised them.
“The second group of rats navigated the maze much faster than
the rats that did not receive omega-3 fatty acids,” Gomez-Pinilla said. “The
DHA-deprived animals were slower, and their brains showed a decline in synaptic
activity. Their brain cells had trouble signaling each other, disrupting the
rats’ ability to think clearly and recall the route they’d learned six weeks
earlier.”
The
DHA-deprived rats also developed signs of resistance to insulin, a hormone that
controls blood sugar and regulates synaptic function in the brain. A closer
look at the rats’ brain tissue suggested that insulin had lost much of its
power to influence the brain cells.
“Because insulin can penetrate the blood–brain barrier, the
hormone may signal neurons to trigger reactions that disrupt learning and cause
memory loss,” Gomez-Pinilla said.
He
suspects that fructose is the culprit behind the DHA-deficient rats’ brain
dysfunction. Eating too much fructose could block insulin’s ability to regulate
how cells use and store sugar for the energy required for processing thoughts
and emotions.
“Insulin is important in the body for controlling blood sugar,
but it may play a different role in the brain, where insulin appears to disturb
memory and learning,” he said. “Our study shows that a high-fructose diet harms
the brain as well as the body. This is something new.”
Still
planning to throw caution to the wind and indulge in a hot-fudge sundae? Then
also eat foods rich in omega-3 fatty acids, like salmon, walnuts and flaxseeds,
or take a daily DHA capsule. Gomez-Pinilla recommends one gram of DHA per day.
“Our findings suggest that consuming DHA regularly protects the
brain against fructose’s harmful effects,” said Gomez-Pinilla. “It’s like
saving money in the bank. You want to build a reserve for your brain to tap
when it requires extra fuel to fight off future diseases.”
